Title: Waterproof connector and injection state detecting method of potting material in waterproof connector using potting material
Inventor: YAMASHITA KAZUNORI
IPC: H01R43/00
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To realize both an improvement in detecting accuracy and cost reduction. SOLUTION: When this potting material 25 injected into a recessed part 18 hardens, a detecting pin 26 advances up to colliding with a surface 25S of the potting material 25. When the potting material 25 does not harden, the detecting pin 26 advances in the recessed part 18 and a clearance part 19, and an advance distance at this incorrect time becomes longer than an advance distance at normal time. The detecting accuracy can be enhanced by enlarging the advance distance of the detecting pin 26 at incorrect time by deepening the clearance part 19. Since the clearance part 19 as a means for improving the detecting accuracy is formed in the shape of partially recessing the recessed part 18, an injection quantity of the potting material 25 can be reduced more than when deepening the whole recessed part.
